Cosigo Resources Ltd. Core results during hydrogeological advancement drilling
Cosigo Resources Ltd. (TSXV: NEX.CSG.h) The management of Cosigo Resources reports that the Company has received the results of core assays from its Taraira North property from a second phase lower slope hole numbered 24TAR_DH_022. The 8698 cm (87m) hole covered the lower strata of the ridges' eastern slope. The company's intent was to accomplish double this depth from a higher collar near the top of the ridge. An innovative approach using RC tools to pass through the uppermost, most fractured and weathered strata (anticipated to be about 8000 cms/80m) and then to switch to full core drilling was intended. The drill hole, designated 24TAR_RCDH_021, did succeed in passing through the upper, broken, 8000 cms/80m but RC drilling efforts were defeated by the following 1000 cms/10m which in part comprised sand and broken rock that appears to have flowed in from nearby historic (and unrecorded) artisanal miners' workings. These recordings and samples will supply a substantial amount of information to understand the porosity of the stratigraphy for the ancillary hydrogeological study. Results from this first upper segment are still pending from the Vancouver laboratory.
Relocating further down slope as 24TAR_DH_022 assisted in avoiding the numerous historical mining adits that seemed to exist near the bottom of 24TAR_RCDH_021.
Cuttings and cores from the recent study were examined by Company geologists who recorded details of rock types, scintillometer counts and magnetism, and panned samples of RC cuttings, preparing them for transport to analytical labs. As a test of the new geological identification method known as 'hyperspectral scanning', the cores were submitted for Quantum Ultrafluroscopic scanning, in Sechelt, BC (near Vancouver) in late November and these results will be expected in mid to late January.

Our study was carried out about 0.20 kms southeast of the first of 12 holes Ingeominas drilled in 1996-97.
The core retrieved from TAR24_DH_022 provided important information about the stratigraphy and revealed a second instance of the previously unsuspected conglomerate seen also in the Gallinero 1 and 2 approximately 0.39 kms to the north west; the remainder comprised of sandstone.
Further studies of this will help the company's technical committee have a better understanding of the stratigraphy, its porosity and fracturing. This will contribute to a more comprehensive hydrogeological picture in the ridge and make important comparisons to existing Colombian government geological surveys of the stratigraphic layering, and confirm, correct, or enhance the detail of those.
Erik Ostensoe, P.Geo., a geological consultant to the Company and a Qualified Person as defined by National Instrument 43-101, has reviewed the TAR24_DH_022 cores and approves the scientific and technical disclosure in this news release.
